The big question is whether they proceed. When I wrote a report on upgraders, Upgrader Alley, last year, it was expected that we would have about eight upgraders within the Edmonton area and that the net consumption of water would be about 80 million cubic metres; in other words, they would take from the river about eight times the volume of water taken by the city of Edmonton. I had real concerns about the implications for the water.
Since the change in the economy, several of those plans have been put on hold or temporarily withdrawn, and I don't now know how many of the upgraders will go ahead. Again I think we need to continue with good monitoring and to get in place a process whereby we can ensure the minimum use of water in the future, if those upgraders do actually proceed.
